Gravitational potential=mgh
=50×10×2.5
=1250J
option a
The equigravity between two planets is determined from the product and their masses and square of distance between them.
<h3>Gravitational force between two planets</h3>
The gravitational force between two planets is calculated as follows;
F = GM₁M₂/R²
where;
- G is universal gravitation constant
- M₁ is mass of first planet
- M₂ is mass of the second planet
- R is the distance between the two planets
Use the mass ratio of the two planets to determine their individual masses.
Thus, the equigravity between two planets is determined from the product and their masses and square of distance between them.

Answer:
Echolocation
Explanation:
.....................................
Energy conservation
mgh = 1/2mv^2
1.5*9.8*3 = 1/2*1.5*v^2
44.1*2 = 1.5*v^2
88.2/1.5 = v^2
58.8 = v^2
v = 7.668 m/s
